It is being 'forced' on the subscribers of some service providers. I believe some of the short coming it is trying to solve is the lack of authentication with DHCP. DHCP was initially designed for a corporate environment and not really a public network. There is some work happening to fill some of the gap. On of the concept behing PPPoE is that the end user and also the service provider infracstructure is already establish to support PPP (because of the existing dial up services) They can reuse their RADIUS server and probably all account management tools they have created around it. Also, in the case of DHCP you mainly have a 'pin down/static' connection. One of the pitch for PPPoE is that you can select different services by login as a different user e.g. user@isp.com to go to my ISP or user@corp.com to access my corporate LAN. So the FreeBSD folks were great enough to give us a PPPoE stack so we could use our favorite OS to access the Internet via our PPPoE enabled service provider (Thanks guys!). So I believe the current implementation is for the client side of PPPoE. I don't think there is a PPPoE server implementation and I don't think there is much use for it but if you want to implement one... Dany p.s. I know a bit on PPPoE but I still consider myself a newbie on FreeBSD. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
